TO ALL WHOM ITMAY CONCERN;

Be it known that 1, JAMES CALI-AN, of Bridgeport, in the county of Fair-field, and State of Connecticut, have invented a new Improvement in Needle-Sharpener Attachment for Sewing-Machines; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, ahd which said drawings constitute part of this specification, and represent, in-- I Figure 1, a side view, and in Figure 2 an end view.

This invention relates to an improvement in the attachment for winding bobbins on sewing-machines, specially adapted to the machine known as the Howe machine.

Those familiar with' the use of sewing-machines, and particularly machines deed for manufacturing purposes, are aware of the great liability to blunt or dull the point of the needle. A common method of repainting the needleis by rubbing upon common oil-stone, 1h i eh often requires so much labor that the needle is thrown away, rather than eicpend such labor.

- Theobject of this invention is to apply to the machine a device for repainting, using the power of the machine for such purpose, and consists in combining with the winding-spindle a grinding-wheel, on which the needles may be repointed or sharpened. I

To enable others to construct my improvement, I'will proceed to describe the same, as illustrated in the accompanying drawings.

I A is the frame, attached to the machine by the pivot B, supporting inone head, G, the adjusting-mandrel I), and in the other head, E, the revolving mandrel F, caused to revolve by bringing a pulley, G, into contact with the fiy-wheel, or by the application of the belt thereto. This device, thus far, is of well-known construction.

To the mandrel F, I fix a wheel, H, in any convenient or known manner, whieh'said wheel is formed so as to present a suitable grinding-surface, and is fixed to the mandrel sons to revolve with it,

When it is desired to rcpoint or sharpen a needle, bring the. mandrel F into connection with the power in the usual manner, which causes the grinding-wheel H to rapidly revolve. Then hold the needle on to the sur face of. the wheel in the usual manner for grinding, and this is accomplished without any additional mechanism,

and at a trifling cost. Q

Having fully described my invention, what I claim asnew and useful, and desire to secure by Letters Patent, is

ln'combinat'ion with a bobbin-winder of a sewing-machine, a grinding-wheel, H, arranged upon the revolving mandrel, substantially in the manner and for the purpose set forth.
